Amazing Extinct Animals (Part 1)

Tyrannosaurus Rex (extinct 65 million years ago)

Tyrannosaurus rex was one of the largest land carnivores of all time, measuring up to 43.3 feet long, and 16.6 ft tall, with an estimated mass that goes up to 7 tons. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small and they retained only two digits.


Quagga: half zebra, half horse (extinct since 1883)

The quagga (Equus quagga quagga) is an extinct subspecies of the plains zebra,which was once found in great numbers in South Africa's Cape Province and the southern part of the Orange Free State. It was distinguished from other zebras by having the usual vivid marks on the front part of the body only. In the mid-section, the stripes faded and the dark, inter-stripe spaces became wider, and the rear parts were a plain brown. The name comes from a Khoikhoi word for zebra and is onomatopoeic, being said to resemble the quagga's call. The only quagga to have been photographed alive was a mare at the Zoological Society of London's Zoo in Regent's Park in 1870.



Thylacine: the Tasmanian Tiger (extinct since 1936)

Thylacine was the largest known carnivorous marsupial of modern times. It is commonly known as the Tasmanian tiger (because of its striped back), the Tasmanian wolf, and colloquially the Tassie tiger or simply the tiger. Native to continental Australia, Tasmania and New Guinea, it is thought to have become extinct in the 20th century. It was the last extant member of its genus, Thylacinus, although several related species have been found in the fossil record dating back to the early Miocene.



Aurochs: (extinct since 1627)

The aurochs or urus (Bos primigenius), the ancestor of domestic cattle, was a type of huge wild cattle which inhabited Europe, Asia andNorth Africa, but is now extinct; it survived in Europe until 1627.


The aurochs was far larger than most modern domestic cattle with a shoulder height of 2 metres (6.6 ft) and weighing 1,000 kilograms (2,200 lb). The aurochs was regarded as a challenging quarry animal, contributing to its extinction. The last recorded aurochs, a female, died in 1627 in the Jaktorów Forest, Poland, and her skull is now the property of Livrustkammaren in Stockholm.




Dodo: the archetype of extinct species (extinct since late 17th century)

The dodo (Raphus cucullatus) was a flightless bird endemic to the Indian Ocean island of Mauritius. Related to pigeons and doves, it stood about a meter (3.3 feet) tall, weighing about 20 kilograms (44 lb), living on fruit, and nesting on the ground.

The dodo has been extinct since the mid-to-late 17th century.It is commonly used as the archetype of an extinct species because its extinction occurred during recorded human history and was directly attributable to human activity.

The phrase "dead as a dodo" means undoubtedly and unquestionably dead, whilst the phrase "to go the way of the dodo" means to become extinct or obsolete, to fall out of common usage or practice, or to become a thing of the past.
